Power Management 303

Redundancy Status and Overall Power Health

The redundancy status is a factor in determining the overall power health.

When the power redundancy policy is set, for example, to AC Redundancy

and the redundancy status indicates that the system is operating with

redundancy, the overall power health will typically be OK. However, if the

conditions for operating with AC redundancy cannot be met, the redundancy

status will be No, and the overall power health will be Critical. This is

because the system is not able to operate in accordance with the configured

redundancy policy.

NOTE: The CMC does not perform a pre-check of these conditions when

you change the redundancy policy to or from AC redundancy. So, configuring

the redundancy policy may immediately result in redundancy lost or a

regained condition.

Configuring and Managing Power

You can use the Web-based and RACADM interfaces to manage and

configure power controls on the CMC. Specifically, you can:

• View power allocations, consumption, and status for the chassis,

servers, and PSUs

• Configure System Input Power Cap and Redundancy Policy for the chassis

• Execute power control operations (power-on, power-off, system reset,

power-cycle) for the chassis

Viewing the Health Status of the PSUs

The Power Supply Status page displays the status and readings of the PSUs

associated with the chassis.

Using the Web Interface

The PSU health status can be viewed in two ways: from the Chassis Graphics

section on the Chassis Status page or the Power Supply Status page.

The Chassis Graphics page provides a graphical overview of all PSUs

installed in the chassis.

To view health status for all PSUs using Chassis Graphics:
